Yeah, the RJ numbering system is yet another example of something
thats completely outgrown its origins and the number itself leaves a
hell of a lot to be desired now. Thats why the 6P4C style system is
used now, much more useful. With RJ11 and RJ45 still used to
loosely describe 6 wide and 8 wide physical bodys.

No problem.

Dunno, it appears to be more that its easier to design them like that.
Basically its easier with all the pins in a horizontal row, both in the input
connector and the output connectors. That automatically means that
you cant go sticking 3 triples into another triple to get a total of 9 tho.

Sure, but I was really talking about stacking say 3 triples into another triple.

Yeah, not much around. And it aint trivial to
google for either, they're called various things.

One that Dave sent me by email is

Bloody thing is $85 retail tho.

Yeah, I'm sure thats why they arent readily
available off the shelf like the triple adapters.

OK, thanks for that, I'll try those today.

Yeah, I was trying to avoid that, Basically going for something
completely different rack wise, made out of 12mm RHS.

The patch panel approach isnt that elegant compared with a
small pcb that you can solder say 10 top entry RJ11 pcb sockets
into. Guess I should just get off my arse and make the pcb.

The main hassle is that since the pins are on a 0.05" pitch,
you cant just use strip board. Unless someone knows of
any 0.05" stripboard. Couldnt find any googling for that.

One other approach might be to butcher 3 triples, break
the plastic away on the single plug side and mount 3 of
those on some 0.01" strip board or just wire between
the pins directly. Specially if only 2 conductors are used,
that might be the easiest approach. Just glue a strip of
plastic down both sides to make the whole thing solid.
